Description: This paper presents a novel segmentation algorithm for metallographic images, especially those objects without regular boundaries and homogeneous intensity. In metallographic quantification, the complex microstructures make the conventional approaches hard to achieve a satisfactory partition. We formulate the segmentation procedure as a new framework of iterative watershed region growing constrained by the ridge information. The seeds are selected by an effective double-threshold approach, and the ridges are superimposed as the highest waterlines in watershed transform. To tackle the over-segmentation problem, the blobs are merged iteratively with the utilization of Bayes classification rule. Experimental results show that the algorithm is effective in performing segmentation without too much parameter tuning. Platform: |

A Novel Merging Criterion Incorporating Boundary Smoothness and Region Homogeneity for Image Segmentation-Abstract
A novel joint region merging criterion combining region homo-geneity and boundary smoothness is proposed. Previous watershed segmentation method which utilizes region homogeneity or edge integrity or both gives good results in some cases. However, for complex scenes such as images of a vehicle with irregular roadside objects reflected on the window panes, it tends to give undesired segmentation results with region boundaries not residing on real physical boundaries. Aiming at improving the segmentation of these complex scenes, we propose the incorporation of an additional measure of boundary smoothness into a new joint criterion. Based on this, an affine transform invariant measure of the smoothness of boundaries is developed, which is the equivalent width of the energy distribution function over frequencies, obtained from Fourier descriptors of the boundary. Experimental results and evaluation are presented in this paper to demonstrate the merits of the proposed method.

Description: 为了提取血管扩张收缩的变化趋势，在采集原始视频AVI图像，进行帧序列转换后，提取血管轮廓成为研究
的重点。文中提出了一种基于标记分水岭对血管超声帧图像的分割方法，该法针对超声图像对比度低、噪声强的特点在标记
之前进行小波域增强。实验证明该法较传统的区域生长法更能准确地提取目标轮廓。基于该法得到的血管在连续时间内截面
积变化曲线，更方便医师进行精确的病理分析。由此可见，该法更适用于超声血管图像的边界提取。
-In order to extract the trend of contraction of vascular expansion, in the acquisition of the original video AVI images were converted frame sequence extracted from a focus of the study of vascular contours. In this paper, based on markers of vascular ultrasound frame watershed image segmentation method, the method for ultrasound image contrast is low, the characteristics of strong noise in the wavelet domain before marked increase. Experiments show that the method is more traditional region growing method to contour more accurately. The law is based on the blood vessels in the continuous-time cross-sectional area within the curve, more convenient and accurate pathological analysis of physicians. Thus, the method is more suitable for vascular ultrasound image boundary extraction. Platform: |
